That same year, the company significantly expanded its Evercare program, a health management program specifically tailored to provide long-term care to older adult patients in assisted living facilities and nursing homes.

At the time, UnitedHealth Group was the largest health insurer in the United States, so the announcement generated significant media attention. Stephen Hemsley, CEO of UnitedHealth Group, noted that the exchanges were too small and risky to be profitable. Hemsley also stated that at the time of his remarks, UnitedHealth Group had lost roughly $475 million in Affordable Care Act exchanges in the previous year and was on track to lose roughly $500 million that year. Though the company planned to pull out from the state market exchanges, Hemsley noted that UnitedHealth Group would continue to advocate for innovative and sustainable approaches that better served the people who rely on the national healthcare market.

On December 4, 2024, Brian Thompson, the CEO of UnitedHealth's insurance division, was shot and killed in New York City. This incident brought significant attention to the company and the broader health insurance industry. Tim Noel, a company veteran, was appointed as the CEO of UnitedHealthcare in January 2025. Also in early 2025, the Justice Department and attorneys general from four states filed a lawsuit to block UnitedHealth's $3.3 billion acquisition of Amedisys, arguing that the merger would reduce competition in the home health and hospice care markets.
